Effect of Instability Resistance Training on Balance, Core Muscle Strength, and Athletic Performance

The 20 intervention actions were divided into three levels (primary, intermediate, and advanced) for instability resistance training and traditional resistance training. Both groups performed training for 60 minutes three times a week. The Swiss ball, BOSU ball, and Wobble boards only provided an unstable surface environment for instability resistance training. The intensity/load was body weight for both training methods.
